Extensions & Conversions in Leighton Buzzard & the surrounding area
A well-built extension is the most cost-effective way to get the space your home is missing — a bigger kitchen, a proper dining room, a downstairs bedroom or study. Watson Carpentry & Building takes on rear and side extensions across Leighton Buzzard and the surrounding area, handling the build from foundations through to the final coat of paint. Callum works closely with you (and your architect or building control, where needed) so you always know what's happening on site and what's next. Homeowners consistently praise the communication, the tidiness of the site, and the quality of the finish — a rear extension client described being 'thrilled with the outcome.' Whether you're opening up the back of a period terrace or adding a family room to a newer build, you get one point of contact and a team that treats your home with respect.

Outstanding attention to detail on our rear extension
Professional, efficient and communicative throughout. The attention to detail was outstanding and the new space complements the house beautifully. I'd highly recommend Callum for any rear extension.
Common questions
Do I need planning permission for an extension?+
It depends on the size and your property — many single-storey rear extensions fall under permitted development, while larger or two-storey work usually needs planning permission. Callum can talk you through what's likely for your home and coordinate with building control; for design and planning submissions you may also need an architect, which he can advise on.
How long does an extension take?+
Every project is different, but Callum will give you a realistic timeline as part of the quote and keep you updated as the work progresses — clear communication throughout is something clients consistently highlight.
Do you handle the whole build or just the carpentry?+
The whole build — from groundworks through to decorating — with one point of contact. Callum coordinates the trades so you're not left project-managing it yourself.
